Cardinals short hops

• Left-hander Tyler Lyons will be promoted from Triple-A Memphis to start Monday’s game against the Mets. Lyons, 26, replaces Joe Kelly, who landed on the disabled list with a strained left hamstring, which he injured running to first base after hitting a groundball.

Kelly’s absence likely will be short term. Otherwise, the Cards would have considered using 22-year-old flamethrower Carlos Martinez, who currently is excelling in late-inning relief -- including contributing multi-inning performances.

Lyons went 2-4 with a 4.75 ERA in 12 appearances (eight starts) for St. Louis last season as a rookie. Right-hander Jorge Rondon will be demoted to clear the roster spot for Lyons.

Jhonny Peralta is off to a slow start at the plate after signing a $53 million deal with St. Louis.

• St. Louis struck quickly in free agency, signing shortstop Jhonny Peralta for four years, $53 million on Nov. 24 despite Peralta returning from a Biogenesis-related suspension. After going 0-for-4 Sunday to extend his hitless streak to 12 at-bats, Peralta’s average has sagged to .172. He has displayed some power, having produced four homers.

• The Cards have an entirely new look to their infield. Last year, it primarily was Allen Craig at first base, Matt Carpenter at second, Pete Kozma at shortstop and David Freese at third. Now, Matt Adams handles first base (with Craig in right field), Kolten Wong and Mark Ellis share second, Peralta is at shortstop and Carpenter is locked into third.

Carpenter, a 2013 All-Star, shifted with the trade of Freese to the Los Angeles Angels. Freese was sent to Anaheim with Fernando Salas for Peter Bourjos and Randal Grichuk.

Adams lifted his average to .357 Sunday with a 2-for-4 game against the Washington Nationals.

The lefty-hitting Wong and righty-hitting Ellis are not in a strict platoon. For instance, Ellis started against the right-handed Stephen Strasburg on Sunday. Ellis had opened the season on the DL with left knee tendinitis. Ellis, who made his Cards debut last Tuesday, was signed to a one-year, $5.25 million deal in December after playing the previous two seasons with the Los Angeles Dodgers.

• Lance Lynn has the best March/April record in MLB history among pitchers with at least 10 starts. He is 11-0 in 12 starts, topping Babe Ruth’s previous-best .929 winning percentage (13-1 in 16 starts). The last unbeaten March/April pitcher was Ray Fisher, who was 9-0 from 1910 through 1920.

• Catcher Yadier Molina has an 11-game hitting streak. He has won six straight Gold Gloves behind the plate.

• The lefty-hitting Jon Jay and righty-hitting Bourjos share time in center field.

• Adam Wainwright, who logged 241 2/3 innings in 2013, retired 18 in a row at one point while tossing a two-hit shutout against the Nats in his last outing. It was Wainwright’s 17th career complete game, which is seventh-most in the majors since 2007.

• Although his arsenal appeared just fine in 2013, right-hander Michael Wacha is trying to incorporate a cutter this season and become a three-pitch pitcher. He also is more frequently flipping a curveball.

• Ex-Yankee Randy Choate has been solid in lefty relief while producing a 1.59 ERA. He has not surrendered a homer since Aug. 1, 2012.

• The Cardinals planned to take a three-car Amtrak train from Washington to New York on Sunday night.
