Pete Alonso belted a tying homer in the ninth inning and Tyrone Taylor delivered a game-winning single to lift the New York Mets to their first win of the season, 2-1 over the Detroit Tigers on Thursday for a doubleheader split.

After blowing a 3-0 lead in a 6-3, 11-inning loss in the opening game, the Mets were held hitless in the second game until Harrison Bader led off the eighth with a single against reliever Tyler Holton.

Alonso’s tying home run – and his 500th career RBI - came off Alex Faedo and Brett Baty walked before Starling Marte sacrificed. Taylor then lined a single to left for his first career walk-off hit.

The win was the first for Mets manager Carlos Mendoza as New York avoided opening 0-6 for the first time since its second season in 1963.

Detroit improved to 5-0 with the Game 1 win, as Colt Keith stroked a tiebreaking double in the 11th before Gio Urshela’s bloop scored a pair.

Matt Manning pitched 5 2/3 hitless innings in the opener with four walks and three strikeouts.

Cardinals rally past winless Marlins

Nolan Gorman highlighted a five-run seventh inning with a two-run double and the St. Louis Cardinals rallied for an 8-5 victory in their home opener to keep the Miami Marlins winless.

The Marlins took a 5-3 lead into the seventh, but the Cardinals scored five times on Ivan Herrera’s RBI single, Gorman’s big hit, Alec Burleson’s two-out, run-scoring single and Masyn Winn’s RBI triple.

Herrera also hit his first major league home run leading off the second inning.

Jake Burger hit a pair of home runs for the Marlins, who dropped to 0-8 for the worst start in the 33-year history of the franchise. Their start is the worst in the majors since Atlanta and Minnesota each opened 0-9 in 2016.

Bibee, bullpen power Guardians

Tanner Bibbee allowed one run over 5 1/3 innings and Steven Kwan had three hits as the Cleveland Guardians spoiled the Minnesota Twins’ home opener with a 4-2 win.

Bibee struck out nine and four relievers followed, with Emmanuel Clase pitching a perfect ninth for his third save. Cleveland's pitchers totalled 15 strikeouts.

Cleveland reached Pablo Lopez for three runs in the sixth. Jose Ramirez singled home Kwan and Tyler Freeman had an RBI single before Will Brennan lofted a sacrifice fly.

Carlos Correa had three hits and Edouard Julien homered for the Twins, who stranded nine runners and were 0 for 12 with runners in scoring position.
