Anderson threw seven innings and gave up one run while recording a career-high nine strikeouts in a 5-1 nightcap win.
"Him being in Triple-A changes nothing on how we view him," Indians manager Terry Francona said before Tuesday's 6-2 victory over the White Sox. "We think he's going to pitch for us for a long time. There's not a lot of pitchers that really come and stay. [Corey] Kluber went back, [Josh] Tomlin went back, [Danny] Salazar went back. He's gonna be just fine. I think you saw [Monday] night what he's capable of."
Anderson was 7-3 with a 3.05 ERA in 15 starts last season, but started this year 0-3 with a 7.99 ERA. He showed an improved curveball and commanded his fastball, and Francona also praised his ability to pitch inside with success.
"He's so far ahead of his experience level, the way he acts, the way he carries himself, things like that," Francona said. "He just got into a little bit of a bind the first handful of starts. … The game was speeding up a little bit. He was trying to get it all back in one inning or one pitch. There was some frustration on his part that we hadn't really seen last year."
He has played second base and all three outfield spots. He was hitting .313 with three doubles through his first 16 at-bats entering Tuesday. And Monday, his throw home to double up Melky Cabrera after a Carlos Sanchez lineout got clocked at 95.3 mph, according to Statcast™.
Martinez has spent parts of 10 seasons in the Minors and parts of six in the Majors, never playing more than 88 games in a season in the the bigs. Francona, though, is a big fan of Martinez's versatility.
"He's more valuable than his numbers," Francona said. "I think when we got him here we felt like he could be a Major League player, and you don't just pigeon-hole him into Triple-A because that's where he's been."
"We wanted to space it out where we're not doing it on the same day," Francona said. "I had kind of sat down with those guys the other day and just kind of walked through this set of games, and just kind of went through what we're going to do."
