In baseball, margins are so fine that basically any outcome is possible on any given pitch, which is — in part — why the regular season is 162 games long to account for randomness. Perhaps no team has encapsulated the volatility of the sport in the early part of the 2026 season more than the Chicago Cubs, who have neither won nor lost more than two games in a row and sit at 5-6.
At 6:40 p.m. ET, Chicago will play its series finale against the Tampa Bay Rays, another team that sits at 5-6 (though they’ve at least won three games in a row). Fittingly, the teams have each won a game so far this series, so tonight’s contest will be a rubber match.
The Cubs will start Colin Rea, while Joe Boyle will toe the rubber for Tampa Bay.
Let’s break down this matchup with some odds and lines at DraftKings Sportsbook.
Chicago Cubs at Tampa Bay Rays prediction, preview
It’s been a disastrous offensive season so far for Chicago, which ranks just 16th in OPS after finishing 2025 seventh in that stat. Some of the Cubs’ best hitters have really struggled, as both Michael Busch and Dansby Swanson are currently below the Mendoza Line, and Pete Crow-Armstrong has just a .638 OPS. Chicago hasn’t had the most difficult schedule to begin its season either, facing three teams that finished outside the playoff picture last season. By that standard, the Rays have had the more impressive start to the season; despite facing the NL’s top-seeded Milwaukee Brewers and now the Cubs, Tampa Bay has the same record as Chicago, and its offense has been much better, ranking seventh in OPS. Individually, Chandler Simpson and Yandy Díaz are tied for the American League lead in hits (17). Neither bullpen has been good: the Rays rank dead last in reliever ERA (7.49), with prized trade acquisition Griffin Jax sporting an 11.25 mark, and the Cubs rank 10th-to-last.
Chicago can avoid turning to its bullpen too early if Rea can provide at least four innings. While he hasn’t started any games this season, he’s pitched three innings of long relief in each of his appearances and was a starter for most of last season, maxing out at seven innings. Though Rea has never finished a season with an ERA below last season’s 3.95, he has some solid tools: his chase, whiff, strikeout, and walk rates all rank among the league’s top quartile this season, and while he posted worse overall metrics in a larger sample size in 2025, his fastball has more induced vertical movement this season. Plus, Tampa Bay isn’t well-suited to take advantage of his weaknesses; though he gives up too many barrels, the Rays ranked fifth-to-last in barrel rate last season, and they’ve been even worse so far in 2026. Junior Caminero’s early season slump should eventually end, which should help Tampa Bay improve its overall pop, but speed and defense specialists Simpson and Cedric Mullins aren’t expected to provide much power. Plus, the Rays still have to adjust to their return to Tropicana Field, since they played at George M. Steinbrenner Field last season, a far more hitter-friendly venue.
Boyle doesn’t have a ton of starting experience, totaling just 24 MLB starts prior to this season, and he was also worth negative WAR last season, getting shelled repeatedly on the road. But Boyle is off to a very hot start in 2026, tossing 6.0 innings of three-hit, two-run ball on March 28 and 5.1 innings of four-hit, two-run ball on April 3. His underlying numbers have also been excellent; in addition to his 3.18 ERA, he sports a 1.65 FIP and a 3.26 expected ERA, and he ranks above the league median in all but three Statcast categories. Some of it is the result of a small sample size, but given his development of a sweeper and his increased reliance on an already-strong split-finger fastball, some could be sustainable. Last season, he was prone to giving up too many hard hits, but the Cubs struggled to generate solid contact and lost Kyle Tucker, who definitely could’ve helped against the right-handed flamethrower. Boyle was also far better at home, notching a 2.15 ERA across 29.1 innings.
Chicago Cubs at Tampa Bay Rays pick, best bet
Best Bet: Chicago Cubs Moneyline (-110)
Both Rea and Boyle are solid starters whose weaknesses align with the weaknesses of their opponents, but Tampa Bay is best off if Boyle can last deep into the game, and he’s only completed the sixth inning five times in his career. I trust Chicago’s bullpen to bounce back more than I do the Rays’: Tampa Bay lost its best reliever, Pete Fairbanks, and Garrett Cleavinger is on the IL.
Strong Lean: Michael Busch 1+ Walks (+108)
Though Boyle has far improved his walk rate this season, in part because he’s thrown all of his pitches in the zone more often. However, he tends to throw his splitter far more frequently against southpaws, and that pitch finds the zone at the second-lowest frequency. Plus, while Busch hasn’t done much well this season, he still ranks in the top sextile in chase and walk rate.
