Tribe seeking consistent effort level from Masterson

BOSTON -- Indians pitching coach Mickey Callaway does not plan on poring over video with starter Justin Masterson in the days leading up to his next start. Right now, Callaway wants to focus on the basics in the wake of the sinkerballer's rough performance on Friday.

Prior to Saturday's game against the Red Sox, Callaway was spotted in the visitors' dugout at Fenway Park, going over things with Masterson. After watching the right-hander's poor two-plus-inning showing in Friday's 10-3 loss to Boston, the pitching coach believes the issue was inconsistent effort level.

"The most glaring thing," Callaway said, "was I just thought his effort level was fluctuating so much that it was hard to repeat [his delivery]. He felt good his previous two starts. He was kind of repeating pretty good. [On Friday], for whatever reason, when he walked that first guy, it seemed like he just started battling himself.

"It was like, 'OK, I'm going to let up to throw strikes here,' and that didn't work. Then, 'OK, I'm going to try to get a little more to throw strikes,' and that didn't work. He never took a consistent approach to try to throw the ball over the plate. I think that's what hurt him the most."

Masterson threw 59 pitches, marking the fewest he logged in a start not cut short by weather or injury. The righty walked four batters, allowed three hits, struck out none and ended with more balls (31) than strikes (28).

That showing came after Masterson spun a 1.72 ERA with a .214 opponents' batting average in his previous three starts combined. For the season, the Tribe's rotation leader is 4-5 with a 5.05 ERA in 15 outings.

"Obviously we want to get back to what he was doing the starts previous to the last one," Callaway said. "We're going to try to talk about just having a little more consistent effort level and a little more energy in his delivery. A little more tempo, a little more energy and a little more intent to let the ball go and trust that it's going to happen."

Crockett more 'comfortable' in second stint with Tribe

BOSTON -- Kyle Crockett found out around midnight on Friday morning that he was leaving Triple-A and going back to the big leagues. The rookie caught an early-morning flight in Ohio, missed a connection in Washington and arrived at Fenway Park shortly before Cleveland's game.

By the third inning, Crockett was back on the mound.

"It's all worth it to be up here," Crockett said with a smile on Saturday. "It was an early morning and a late night, and it's hard to sleep when you're that excited."

The 23-year-old Crockett was pressed into duty in the third inning of Friday's 10-3 loss after starter Justin Masterson labored in a two-plus-inning effort. The young lefty took over and allowed a two-run double to Mike Napoli -- both runs were charged to Masterson -- but he recovered to log 1 2/3 innings to help Cleveland's bullpen.

Between two stints with the Tribe this year, Crockett has a 1.50 ERA in six innings (four appearances).

"I thought he showed very good poise in a tough situation," Indians manager Terry Francona said. "I thought he made one bad pitch to Napoli. Other than that, I thought he was tremendous."

Crockett -- Cleveland's No. 15 prospect -- was originally called up from Double-A Akron on May 16, becoming the first player from any team's 2013 Draft class to reach the Majors. In 21 appearances combined between Double-A and Triple-A this season, the left-hander had a 0.74 ERA with 23 strikeouts, three walks and a .172 opponents' average in 24 1/3 innings.

"I'm a lot more comfortable," Crockett said of being called up the second time. "It's the same game. These guys, you just know that they're better hitters and better players. You just have to do what you do. Hopefully I can just stick to what I've been doing and keep getting the job done."

Quote to note

"I was an 11-year-old that had gone to heaven before his time. For me, I couldn't think of a better way to grow up. It's all I ever wanted to do. I'm sure my dad had something to do with that, but it wasn't like he had to drag me to the ballpark. I was waiting."
-- Francona, on being at the ballpark with his dad, Tito, during his playing career

Smoke signals

• Since being activated from Major League Baseball's concussion list on June 6, Carlos Santana had a .286 average with an .894 OPS in eight games, entering Saturday. Over his past 12 games, Santana was hitting .300 (12-for-40) with three homers, two doubles, 11 RBIs, 11 walks and a 1.037 OPS for Cleveland.

"Carlos has kind of a unique swing to begin with," Francona said. "For a guy that's able to take walks like he does and not strike out, there's a lot of movement and some of it can get almost harsh, aggressive. But since he's come back, I think he's been a little quieter."

• Indians right-hander Zach McAllister, who is currently on the 15-day disabled list due to a lower back strain, is scheduled to make a Minor League rehab start for Triple-A Columbus on Saturday night. Following the outing, Cleveland will re-evaluate McAllister and determine the next step for the righty.

• Outfield prospect Clint Frazier (selected in the first round of the 2013 First-Year Player Draft) went 2-for-4 for Class A (low) Lake County on Friday, giving him a .310 average and .879 OPS through 11 games in June. Frazier hit .241 with a .664 OPS in the first two months this season.

• The Indians have signed right-hander Jared Robinson, who was selected in the 11th round (338th overall) out of Cerritos College (Calif.) in the First-Year Player Draft earlier this month. Cleveland has now reached deals with 14 of its 42 picks.
