Blue Jays right-hander Marcus Stroman may be just 23, but he's pitching well beyond his years. Since joining Toronto's rotation May 31, Stroman is 5-2 with a 2.21 ERA.
Even manager John Gibbons has a hard time believing it.
"[Stroman's] pitching like a veteran who has been around a long time," Gibbons said. "He has the great arm, he has the pitches and all that, but the big thing about him is that he is a great competitor."
The leaps and bounds the right-hander's made were especially evident in his last start against the Red Sox. He carried a no-hit bid into the seventh inning and extended his scoreless innings streak to 14 with a one-hit gem.
"Last game, I didn't shake once. The previous game, I maybe shook one or two times," Stroman said. "There's not much shaking going on."
He'll face the Red Sox and right-hander Rubby De La Rosa for the second straight start Tuesday at Fenway Park.
De La Rosa surrendered a career-high seven runs (six earned) on nine hits Thursday at Rogers Centre for his third loss this season.
"Every pitcher tries to make his best pitches," De La Rosa said after the start. "It's a little complicated. What happened today, I'll try not to think about it and look forward to the next one."
The outing once again showed the stark contrast between De La Rosa's success on the road and at home. He's 0-3 with a 6.04 ERA on the road and 3-0 with a 1.38 ERA at Fenway.
"Clearly, he feels comfortable on the mound at Fenway and is able to channel the emotion and adrenaline inside Fenway Park," Red Sox manager John Farrell said. "We've got to do something to try and even out the splits as they stand."
Blue Jays: Trade helps with infield depth
• Toronto acquired infielder Danny Valencia from Kansas City in exchange for catcher Erik Kratz and right-hander Liam Hendriks on Monday.
Valencia can expect to see some starts at third until Brett Lawrie returns from the disabled list. However, his role remains uncertain.
The 29-year-old Valencia is a career .265 hitter with a .304 on-base percentage. A part-time player with the Royals this season, he appeared in 36 games, but was especially valuable against left-handed pitching.
Red Sox: Webster tabbed for Saturday start
• Farrell said on Monday that right-hander Allen Webster will make his second start Saturday against the Yankees.
Webster pitched Sunday against the Rays, taking Jake Peavy's spot in the rotation after he was dealt to the Giants. Webster allowed two runs on three hits in 5 1/3 innings and picked up the win in his season debut.
"Everything points to Allen making that start. There's no plans right now to make any changes in our rotation," said Farrell.
• The Red Sox's 14-1 loss on Monday to the Blue Jays marked the team's widest margin of defeat this season and the most lopsided loss at Fenway since a seven-inning, 13-0 setback against the A's on April 23, 2013.
• Jose Bautista has 28 home runs against the Red Sox, 18 of which have come at Fenway.
• The Red Sox lead the American League with 20 one-run wins. The club also has 20 one-run losses, which is tied for the AL lead.
