BOSTON -- An American record in the men’s 600 meters and a world-leading women’s shot put highlighted an exciting final day of the USATF Indoor Championships at the Reggie Lewis Center on the campus of Roxbury Community College. Saturday and Sunday attendance totalled 6,091 for the event broadcast live on USATF.TV and NBCSN.
 
Casimir Loxsom (Seattle, Washington) was in command from the gun in the men’s 600m, sprinting to the front and passing 200m at 23.76 and 400m at 48.26 to close for the American Record and the win in 1:15.33. He clocked the fourth-fastest time ever and was a quarter-second better than his own AR set Jan. 24 at Albuquerque. Behind Loxsom, Mark Wieczorek (Seattle, Washington) had the fastest final lap overall at 26.59, and he grabbed second in 1:16.07.
 
Recording the three longest throws in shot put the world this year, Michelle Carter (Ovilla, Texas) won her third consecutive national indoor title after throwing 19.45m/63-9.75 in the sixth round. Carter took the world lead in the second round, and she improved that mark in the fourth round before uncorking her best effort on her final throw. Becky O’Brien (Cumberland, Maine) set a lifetime best of 18.34m/60-2 in round four to finish second.
 
Cruising with two laps to go in the women’s 2 mile, Jordan Hasay (Portland, Oregon) remained the leader with teammate Shannon Rowbury (San Francisco, California) close behind her. The pair created a sizeable lead above the field heading into the final lap, where Rowbury made a move on the back stretch. As Hasay held strong, Rowbury’s kick earned the win in 9:43.95.
 
Marvin Bracy (Clermont, Florida) ran the most technically-proficient race to defend the 60m title he won last year at Albuquerque, winning in 6.55. Ryan Bailey (Tualatin, Oregon) and Trell Kimmons (Coldwater, Mississippi) stumbled early in the race to open the door for Bracy, while Joe Morris (Tualatin, Oregon) was second in 6.57.
 
Winning a second straight and third overall 60m title, Tianna Bartoletta (Tampa, Florida)  ran a powerful 7.08, which was the second-fastest time in the world this season and the fastest run by an American. Jessica Young (Columbia, South Carolina), the previous U.S. leader, was second in 7.16.
 
Lauren Wallace (Sacramento, California) squeaked through an inside opening over the final stretch of the 1000m to capture her first USATF Championship in 2:40.42. Wallace was at the front of a tight pack through 600m before dropping back over the next lap, yielding to Charlene Lipsey (Baton Rouge, Louisiana) and Stephanie Charnigo (Flanders, New Jersey) at 800m. As Lipsey drifted wide off the final turn, Wallace pushed through and outkicked Treniere Moser (Portland, Oregon) and Stephanie Brown (Springdale, Arkansas), who both clocked 2:40.62 with the edge going to Moser.
 
In the highly anticipated women’s pole vault competition, collegian Demi Payne (Nacogdoches, Texas) of Stephen F. Austin State University won her first USATF Championship, clearing 4.55m/14-11 on her third attempt. Mary Saxer (Boston, Massachusetts) passed at that height, but missed three times at 4.60m/15-1. She finished the event in second place at 4.50m/14-9. World record holder Jenn Suhr (Churchville, New York) was nursing a heel injury coming into the championships and was not able to compete at full speed, withdrawing after two attempts at 4.60m/15-1.
 
In the Nike men’s mile, Matthew Centrowitz (Portland, Oregon) led the first two laps before Riley Masters (Seattle, Washington) took over to lead the field through 1000m. Centrowitz and Ben Blankenship (Eugene, Oregon) then made a move with Pat Casey (Eugene, Oregon) before Centrowitz regained the lead with two laps to go. At  the bell, a leading Centrowitz had Blankenship nipping at his heels. Centrowitz clocked 26.31 in the final 200 meters for a finishing time of 4:01.40 with Blankenship in second at 4:02.14 and Casey in third in 4.02.85.
 
Six months after giving birth, Alysia Montaño (Valencia, California) made a triumphant return to the track, taking the crown in the women’s 600m in 1:26.59. Ajee’ Wilson (Philadelphia) led through the first lap just ahead of Montaño before Montaño assumed the lead at 400m in 55.76. As Montaño controlled the pace on the final backstretch, Wilson’s foot clipped the leg of a trailing Kendra Chambers and the two fell to the track. From there it was all Montaño for the win with Phoebe Wright (Signal Mountain, Tennessee) closing quickly to take second in 1:28.00.
 
AG Kruger (Ashland, Ohio) saved his best for last in weight throw, tossing 23.41m/(76-9.75) to win his ninth national indoor title and his 14th overall. J.C. Lambert (Harrisburg, Illinois) became the leader in round three with his best throw of 23.35m/(76-7.25) to finish in second place.
 
Omar Craddock (Gainesville, Florida) won his first national indoor gold in triple jump after Saturday’s long jump winner and Craddock’s former Florida teammate Will Claye was forced to withdraw from the event due to injury. Craddock was second after the opening round, and popped a 16.59m/54-5.25 on his next attempt to take the lead for good. He stretched his lead on each of the next four jumps, finishing with a 16.84m/55-4 leap in round six to win by almost a foot with five of his six jumps good for the title. Chris Benard (San Diego, California) leaped 16.57m/54-4.5 in round five for second place.
 
Chaunté Lowe was a resounding winner in the women’s high jump, clearing 1.88m/6-2 on her first try en route to a fourth USATF indoor title. Lowe won the outdoor national title last year and today competed in her first full indoor season in three years. Also competing was five-time Olympian Amy Acuff (Austin, Texas), who finished second at 1.82m/5-11.5 in the midst of a comeback after three years away from the sport.
 
A slow early pace in the men’s 1000m saw Robby Andrews (Manalapan, New Jersey) lead through 400m in 58.69. Trying to up the tempo, James Gilreath (The Woodlands, Texas) made a strong move on the next lap and passed 600m in 1:27.97. Cory Leslie (Huron, Ohio) pushed past Gilreath as he and Kyle Merber (Annandale, New Jersey) controlled the race at the front. The two battled into the final turn, where Andrews used his patented storming finish to pass them both and run away with the win in 2:21.91.
 
Already the fastest American this season, Aleec Harris (Atlanta, Georgia) was a smooth and decisive winner in the men’s 60m hurdles, taking the title in 7.51, with Jarret Eaton (Baltimore, Maryland) second in 7.59. Harris, the NCAA silver medalist in the 110H for USC last year, was with the leaders at the first hurdle, but he moved ahead to capture his first USATF indoor gold.
 
Jasmin Stowers (Liberty, South Carolina) ran away from the field over the final three barriers to win the women’s 60m hurdles final in a lifetime-best 7.84. Her finish is the second-fastest time in the world this year. Stowers’ former LSU teammate Tenaya Jones (Rowlett, Texas) finished second in 8.03, and Tiffani McReynolds (Waco, Texas) was third in 8.06.
 
Amanda Smock (Minneapolis, Minneapolis) defended her triple jump title, with a hop, skip and jump to 13.28m/43-7. Keena Wolter (Santa Maria, California) was second with a mark of 13.16m/43-2.25)
 
Maria Michta-Coffey (Nesconset, New York) led from start to finish in the women’s 2 mile race walk, breaking the tape at 13:37.02 to claim her second USATF title during the 2015 indoor season.
