Signed for pop, Peralta making noise with glove

ST. LOUIS -- Those skeptical of Jhonny Peralta's defensive ability upon the Cardinals' offseason signing of the veteran shortstop haven't been heard much in recent weeks, as Peralta is proving himself not only to be a capable shortstop but one of the better ones in the league.

Though signed for the pop he'd bring to the position, Peralta has given the Cardinals plenty of coverage. He entered Monday ranked fifth among all Major League shortstops with a 3.5 Ultimate Zone Rating and tied for second with eight defensive runs saved. In that latter category, he is tied with Kolten Wong for the highest such number among all Cardinals position players.

Peralta actually has a better UZR and higher DRS total than Atlanta's Andrelton Simmons, considered by many to be the gold standard at short. Simmons was also the Platinum Glove winner last season.

Asked if Peralta's defense has been even steadier than projected, manager Mike Matheny answered, "I agree. I think he's getting better, it seems, like every game. I don't know what the explanation would be, but he looks very good."

Peralta, a 12-year veteran in his first season in the National League, simply cited comfort.

"I feel better at shortstop," Peralta said. "I know more about the players for the other team, and I know how to be in the [right] position. I feel more comfortable now."

Siegrist not overly concerned about injury

ST. LOUIS -- Left-handed reliever Kevin Siegrist downplayed concern about his injured left forearm/wrist on Monday when addressing the issue for the first time since being placed on the disabled list on Saturday.

Siegrist described the area near his wrist as "still sore, but getting better." There was still evidence of bruising.

Siegrist first felt the tightness after his appearance on May 18. When he next pitched, five days later, he still couldn't get his arm to loosen up as usual. That necessitated further testing, none of which has raised concern about the injury potentially extending to his elbow.

"I'm trying to take precaution with it," Siegrist said. "I threw in the game in Cincinnati, and it wasn't getting better. We decided to take a look at it. It's tight after I release the ball, and it would just stay tight. That's pretty much it."

The Cardinals have prescribed a program of rest and rehab for Siegrist, who will be eligible to come off the DL on June 8.

Memorial Day recognized at Busch Stadium

ST. LOUIS -- As part of Major League Baseball's efforts to remember those who died in service to the country, the Cardinals and Yankees wore specially designed caps and jerseys that featured a camouflage script. The two clubs also paused during their pregame preparations to participate in the National Moment of Remembrance, a moment of silence held at around 3 p.m. CT.

The military-style caps and jerseys are available for purchase; MLB and MLB Advanced Media have pledged to donate all of the net proceeds from the items to Welcome Back Veterans, which provides grants to university hospitals throughout the country that provide treatment for post-traumatic stress disorder and injury to veterans and their families.

Since the program began in 2008, MLB has donated more than $30 million to Welcome Back Veterans.

The Cardinals also had a bald eagle from the World Bird Sanctuary circle Busch Stadium several times while members of the military unfurled an American flag just beyond center field.

Worth noting

Tyler Lyons (strained left shoulder) continues to throw on flat ground but still does not know when he will resume throwing off a mound. He has been on the DL since May 13.

• Memphis ended a five-game losing streak on Sunday behind starter Scott McGregor, who earned his first Triple-A win. McGregor (1-5) allowed one run on five hits and a walk in six innings. Both Stephen Piscotty and Scott Moore contributed two-hit games. Outfield prospect Randal Grichuk drove in two.

• Monday's game against the Yankees marked the first of 20 Interleague contests the Cardinals will play this season. They are 135-120 since the introduction of Interleague Play; the only National League team with a better winning percentage is Atlanta.
