The first-place Cleveland Guardians can extend their American League Central Division lead when they visit Detroit to face the slumping Tigers for the first of a four-game series Monday.

Cleveland has won five of its last six games, including a 10-3 pounding of the Cincinnati Reds on Sunday. The Tigers have lost 10 of their last 12 games.

Framber Valdez (2-2, 4.32 ERA) will start the opener of the four-game series for Detroit. The veteran left-hander delivered a solid performance in his previous outing after serving a five-game league suspension for beaning a Boston batter.

Valdez limited the New York Mets to two runs and five hits while striking out seven in 6 2/3 innings last Wednesday.

"Framber was dominating both sides of the plate," utility man Zach McKinstry said. "It's fun to play behind him when he's dominating like that."

Valdez was working with a one-run lead before issuing a two-out walk to the Mets' No. 9 hitter, Luis Torrens, who eventually scored the tying run.

"This start mattered to him, just getting him back into the season," manager A.J. Hinch said. "He worked hard to get into the game and I thought he threw the ball extremely well. The two-out walk will haunt him and it'll haunt us a little bit. But we asked a ton out of him (Wednesday) and he delivered."

Valdez has been a Guardians killer during his career. He's won all five of his appearances (four starts) against them, posting a 2.30 ERA.

He will be opposed by right-hander Slade Cecconi (2-4, 5.60). It's been a rocky beginning to the season for Cecconi, who has allowed four or more earned runs in five of his nine starts.

He has shown signs of improvement in his last two starts. Cecconi limited the Kansas City Royals to two runs in 5 1/3 innings, then tossed four scoreless innings against the Los Angeles Angels. He posted seven strikeouts but required 89 pitches to record 12 outs.

He's 1-1 with a 2.25 ERA in two career starts against the Tigers.

Valdez will try to cool down Angel Martinez. The Guardians outfielder has been on a power surge, homering in four of his last five games. He'll carry a six-game hitting streak into the contest. He's scored eight runs and knocked in eight during that span.

Martinez has nine homers this season, compared to 11 in 139 games last season.

"Honestly, I'm trying to not get too high," Martinez said. "(Whether) you're having a good day, you have a good week, good month, I try not to get too high. This game can humble you really quick. I'm just enjoying the moment, and what happened today, it doesn't matter tomorrow."

Manager Stephen Vogt believes Martinez's improvement is a natural progression for the talented 24-year-old.

"I think every young hitter continues to grow and understand, 'If I can shrink the strike zone, and I can bring that pitcher into the strike zone, I've got a lot better chance to hit it hard,'" Vogt said. "We've seen Angel struggle with chase at times. But when he does keep that pitcher in the zone, man, is he dynamic and hits the ball hard."
