KANSAS CITY -- After losing six of their last seven games in April, the Blue Jays tweaked their roster on Thursday by selecting the contract of infielder Steve Tolleson and recalling outfielder Anthony Gose from Triple-A Buffalo, while optioning infielder Jonathan Diaz to Buffalo and designating outfielder Moises Sierra for assignment.
Tolleson, 30, appeared in 19 games for the Bisons, batting .236 with one home run, nine RBIs, 12 walks and a .345 on-base percentage. The 5-foot-11, 185-pound right-handed hitter has played in 54 Major League games for Oakland and Baltimore over two seasons, posting a .225 average with three home runs and 10 RBIs.
Gose, 23, batted .235 for Buffalo in 19 games, walking 12 times in 68 at-bats for a .350 OBP. The Paramount, Calif., native has spent parts of the past three seasons with the Blue Jays, hitting .238 with three home runs, 23 RBIs and 20 stolen bases in 109 games.
Sierra was just 2-for-34 after going 0-for-4 with two strikeouts as the designated hitter in Wednesday's 4-2 loss to the Royals.
"[Sierra] was scuffling," said Blue Jays manager John Gibbons. "In all fairness to him, the role he was in didn't allow him to get steady at-bats. That's awful tough on a young guy trying to establish himself."
Gibbons said the Tolleson-for-Diaz switch is designed to create a little more infield offense and Tolleson's versatility could come in handy with upcoming Interleague series against the Pirates and Phillies.
"We're looking to beef up the offense a little and it adds a little team speed," Gibbons said.
Gose enjoys stellar return against Royals
KANSAS CITY -- Anthony Gose doesn't know what his sudden promotion to the Blue Jays from Triple-A Buffalo will mean over the long haul. But for now, Gose is just glad that he has at least temporarily escaped the cold Buffalo weather and gets another opportunity to make an impression at the Major League level.
With Melky Cabrera nursing a left knee contusion after being struck by a Danny Duffy pitch on Wednesday, Gose gives manager John Gibbons some flexibility with his outfield personnel. Gose was in the lineup on Thursday in left field and batting ninth against the Royals.
It was an impressive first night back for Gose, who went 2-for-4 with a two-run double in the Blue Jays' 7-3 win. Gose also showed excellent range in left field and threw out Eric Hosmer trying to score from second on a single in the third inning.
Gose was hitting .235 at Buffalo with a .350 on-base percentage thanks to 12 walks. He also had four steals. In 2012, Gose hit .223 for the Blue Jays in 56 games. Last year, he appeared in 52 games for Toronto and hit .259.
Because of previous stints with the Blue Jays, Gose is hopeful he can draw on that experience whenever he sees his name in the lineup.
"I've learned a lot, especially offensively," Gose said. "I don't know if this time is any different than last time, because I don't know what this time is. If you have a hole in your swing up here, the pitchers are going to expose it. You better figure it out soon or else you're going to be back down freezing in Buffalo."
Gibbons said that with Gose or any other player, the ability to stick in the Majors simply comes down to producing in a timely manner.
"There has to be an opportunity and when you get it, you have to take advantage of it," Gibbons said. "We've got our three guys in the outfield, but [Gose] could fit in as the fourth guy. We know he's good on the bases and can play some defense. But it's all about production. That's why it's so hard to make it in the big leagues and stay for any length of time."
Gibbons set up to employ six-man rotation
KANSAS CITY -- The Blue Jays are now in position to go with a six-man rotation for the immediate future after manager John Gibbons announced that left-hander J.A. Happ will be making a start on Monday against the Phillies.
Right-hander Dustin McGowan earned another start with a three-hit effort over six innings against the Royals on Tuesday and will work on Sunday against Pittsburgh. Gibbons could dial back to a five-man rotation if he sees something he doesn't like in upcoming days or bring up top pitching prospect Marcus Stroman, who has been electric at Triple-A Buffalo.
"We'll pitch Happ on Monday night and see where that takes us," Gibbons said.
