CHC@PIT: Grimm fans Byrd to escape a bases-loaded jam

SAN FRANCISCO -- The Giants' Angel Pagan singled to lead off the eighth inning Monday against Jeff Samardzija, and Cubs manager Rick Renteria called on Justin Grimm to face the Nos. 2-4 hitters.

"I was honestly a little surprised yesterday when they called my name," Grimm said Tuesday. "They didn't have to say it twice."

On May 20, he was the pitcher Renteria wanted when the Yankees had runners at first and second and two outs in the sixth. Grimm got Alfonso Soriano to hit into a fielder's choice.

"I feel like after the circus I had in St. Louis, it was just a matter of gaining confidence in me again and seeing how I respond when I go out," said Grimm, who took the loss in an extra-inning game against the Cardinals May 13, losing on a walk-off hit by pitch. "That's my opinion. I'm still learning and just trying to be ready every day. You never know what's going to happen."

Like having to face the Giants' Hunter Pence, Buster Posey and Pablo Sandoval, which he did on Monday.

"I try to take that out of it," Grimm said. "When you first come up, you see all these big names and you do tend to shy away sometimes. Basically, my mindset is to attack the zone and not break it down to, 'All right, I have to get this ball outside right here, I have to get this ball inside.' I want to attack the zone and quit trying to strike everybody out. Strikeouts happen. You can't make them happen, they just happen."

Grimm, who leads the Cubs with 24 relief appearances, struck out Pence and Sandoval, by the way.

Castillo impressed by Samardzija's latest start

CHC@SF: Samardzija fans 10 in first win of 2014

SAN FRANCISCO -- Jeff Samardzija got his first win of the season on Monday, ending a 16-game winless streak, and what impressed Cubs catcher Welington Castillo was that the right-hander did not walk a batter over seven innings.

"He was able to throw all his pitches in any count," Castillo said Tuesday of Samardzija, who is second in the National League in ERA. "He just went out like his other starts. All of his pitches were working. He was throwing the ball really good, with a lot of good breaking balls, good fastballs on the hands. There were just a couple mistakes with [Pablo] Sandoval."

The Giants' slugger hit an RBI single in the first and a two-run homer in the fourth off Samardzija, but the Cubs won, 8-4. The eight runs were a surprise. The Cubs had scored eight in Samardzija's five previous starts combined.

Samardzija was the first pitcher to enter play on Memorial Day leading a league in ERA, but without a win since Hall of Famer Bruce Sutter did so in 1977.

A fielding error by Samardzija in the first led to the Giants' first run.

"If we make that play, he wouldn't have faced Sandoval that inning, and he would've led off the next inning," Castillo said. "With nobody on, no outs, [Samardzija] could have gone right at him. The thing is, when you have a hitter like that, you want to pitch carefully and that's when the mistakes come because you're trying to be too perfect. Hitters like [Sandoval] get you."

It was Samardzija's second start this season in which he did not walk a batter, and that's part of his effort to be more efficient and reduce his pitch count.

"It's like he said in Spring Training, he wants to stay out of high pitch counts, and go right at the hitters and let them put the ball in play," Castillo said of the right-hander. "He's been really good in that area."

Extra bases

• Josh Vitters' injury problems continued Tuesday when Triple-A Iowa placed him on the disabled list, effective May 24, with a broken big toe on his left foot. He was injured when he fouled a ball off his toe during batting practice.

Vitters, who was limited to 28 games last season because of injuries, was batting .208 (30-for-144) with six home runs and 20 RBIs in 43 games at Iowa.

• Infielder Arismendy Alcantara, ranked No. 6 on MLB.com's list of top 20 Cubs prospects, was scheduled to make his first professional start in the outfield on Tuesday, but Iowa's game against Memphis was postponed because of rain. The Iowa team is short-handed as far as outfielders go with Vitters being injured. Ryan Kalish, optioned to Iowa on Monday, had yet to report to the Minor League team.
