UNDATED (AP) — The Big 12 is facing an identity crisis at quarterback. There will be a lot of new faces next fall. Seven of the league’s 10 teams had senior quarterbacks. Five of them started every game last season. Iowa State coach Paul Rhoads said Tuesday there’s a “little bit of unknown” until all the new quarterbacks show what they can do for their teams. But he says there’s no lack of talent.

The most experienced Big 12 quarterback is Texas junior David Ash, who has started 18 of his 25 games for the Longhorns. Casey Pachall is back at TCU, where he started 17 of 25 games, including the first four last season before leaving school for substance abuse rehabilitation.

WASHINGTON (AP) — Adam Wainwright extended his sterling start to the season — and Washington’s mediocre one — by coming within two outs of his second shutout, leading the St. Louis Cardinals past the Nationals 2-0 Tuesday night. The right-hander (4-1) lowered his ERA to 1.93 by going 8 1-3 scoreless innings, allowing only five hits. Edward Mujica got the final two outs for his third save. Allen Craig and Carlos Beltran drove in runs in the fourth off Nationals lefty Ross Detwiler (1-1), who gave up eight hits across six innings.

The Nationals, who led the majors with 98 wins last season and were a popular pick to do well in 2013, lost for the eighth time in their past 11 games to fall to 10-10.

KANSAS CITY, Mo. (AP) — The Kansas City Chiefs have been on the clock since the end of last season. The Chiefs went 2-14 to land the No. 1choice in the NFL draft for the first time in franchise history. But there’s no clear-cut player available this year, and certainly no star quarterback such as Andrew Luck or Robert Griffin III to make the pick an easy one.

Kansas City is likely going to shore up its offensive line with the selection Thursday night. Most draft experts believe the Chiefs will go with Texas A&M’s Luke Joeckel or Central Michigan’s Eric Fisher, a pair of left tackles who could protect quarterback Alex Smith. The Chiefs are also open to trading out of the No. 1pick.

COLORADO SPRINGS, Colo. (AP) — USA Swimming will choose between Omaha, Neb., San Antonio and St. Louis as the site for the 2016 Olympic swimming trials. The national governing body says it will announce the host city on Saturday. Omaha has hosted the last two trials, in 2012 and 2008. Last year’s eight-day event was attended by more than 164,000 fans and the meet was broadcast live in prime time on network television. Two temporary pools were built inside the CenturyLink Center for the event.

In 2004, the trials were held in Long Beach, Calif., the first time they were held outdoors in temporary pools. In January, USA Swimming said six cities were bidding to host the trials. Former host Indianapolis, along with Greensboro, N.C., and Jacksonville, Fla., were eliminated after an evaluation team from USA Swimming, along with an outside member of the group’s board, visited each location.
