CINCINNATI (AP) — Yandy Díaz homered on the third pitch of Levi Stoudt's big league debut to spark a six-run first inning, and the Tampa Bay Rays routed the Cincinnati Reds 8-0 Wednesday to improve to a major league-best 16-3.

Tampa Bay pitched its second straight shutout and has six this season, more than half the Rays total of 10 for all of last year. Tampa Bay tops the big leagues with 133 runs and has allowed 50, tied for the big league low entering the day.

Reds manager David Bell was ejected in the ninth inning by plate umpire Erich Bacchus after coming onto the field to argue. Pete Fairbanks threw his first pitch to Stuart Fairchild behind the batter's head, then threw a 2-0 pitch up and in.

The entire three-game series drew 31,794, including 10,205 for the series finale and 7,375 for the series opener, the Reds lowest for a home game since May 1, 1985, at Riverfront Stadium, according to baseballreference.com.

Drew Rasmussen (3-1) allowed three hits and three walks in five innings with seven strikeouts. Josh Fleming pitched three innings and Fairbanks finished a five-hitter.

Cincinnati dropped to a season-worst four games under .500 at 7-11 and was held scoreless in consecutive games for the first time since three in a row in April 2019 against Milwaukee and Pittsburgh. The Reds totaled nine hits in their last two games, all singles.

Randy Arozarena had three hits and is hitting .333 for the Rays, who have won three of four following consecutive losses.

Stoudt (0-1), a 25-year-old right-hander acquired from Seattle in last summer's trade that sent Luis Castillo to the Mariners, allowed seven runs, nine hits and one walk in four innings with three strikeouts, leaving him with a 15.75 ERA. He threw 36 pitches in a top of the first that took 16 minutes.

Díaz turned on an up slider and drove a line drive over the left-field wall for his sixth homer this season, Tampa Bay's big league-high 42nd. Isaac Paredes had an RBI double, Josh Lowe a two-run single and Manuel Margot an RBI double. Stoudt also balked home a run.
