The Toronto Blue Jays meet the Tampa Bay Rays on Monday, May 4, and Vladimir Guerrero Jr. enters the matchup in good shape after a two-hit game in the series finale against the Twins. He has been among the leaders in hits and batting average this season, and the matchup with Rays starter Nick Martinez gives Toronto’s best hitter a clear path to be involved early.
Martinez takes the mound with a 1.70 ERA, but the numbers underneath that run prevention point to a more vulnerable profile. His 3.85 xERA, xBA in the 42nd percentile, ninth-percentile whiff rate and 17th-percentile strikeout rate all suggest hitters have been able to make contact, and the Blue Jays’.304 team average against sinkers is a direct concern because Martinez leans on that pitch more than anything else.
Guerrero has done damage against sinkers all season, carrying a.438 average and a.469 slug-rate against the pitch. That matters here because Martinez’s most-used offering is the sinker, and the contrast between the right-hander’s surface results and his weaker underlying metrics is the kind of split bettors look for in a matchup like this. Toronto is also listed at Blue Jays +1.5 (-180), while the Rays are at Rays -1.5 (+155), reflecting a game that is expected to stay tight even with Tampa Bay holding the home edge.
The case for Guerrero is not just the matchup, either. He is coming off that two-hit game against Minnesota, and Toronto has already shown it can punish this type of pitching. Martinez has not allowed a home run in three straight games, but that clean stretch sits beside weaker contact indicators, and that is where the tension in this preview lives: good run prevention, shaky underlying numbers. Guerrero said he is expecting Martinez to keep producing for the Blue Jays tonight, and the hitters around him have a chance to make that belief carry real weight.
For Toronto, the path is simple. If Guerrero gets the kind of sinkers he has handled so well, the Blue Jays should have chances to keep the game close and put pressure on a Rays staff that is being asked to trust a starter whose results and indicators do not fully match.
