Donnie Stevenson seems as recent as Mettle the Mule, but Ken Rosenthal offers an addendum to dazzling if brief career of the hitting approach coach who was not so long ago the talk of the town. Donnie Stevenson was Pete Alonso. Multiple sources confirm it was the Mets' first baseman who fired up his fellow hitters on May 1 before they faced their former teammate, Phillies right-hander Zack Wheeler. The Mets won 5-4 on a go-ahead homer by Michael Conforto in the top of the ninth inning – the first victory of a 7-2 run that has vaulted them to the top of the NL East. “Donnie's been great helping the team,” Alonso said afterward, describing “Stevenson” as a “nice new hire,” “great hitting/approach coach” and all-around savior. “Donnie really helped us today.” Alonso, in assuming his alter ego, wore a hat and sunglasses to the hitters' meeting, then delivered the most basic of messages, according to some in attendance: Let's stop over-thinking things. Let's just go out there, stick to our strengths and let it rip. The meeting, according to one attendee, lasted about four minutes. The players did not even talk about Wheeler, laughing, clapping and hooting instead. The results of Alonso's attempt to loosen up a tight club were impressive – the Mets scored four runs in seven innings against Wheeler, matching the most he has allowed this season. Two days later, after a 6-5 loss in St. Louis, the team fired hitting coach Chili Davis and assistant hitting coach Tom Slater. But the emergence of “Donnie” had nothing to do with those moves. As Joel Sherman reported in the New York Post, team president Sandy Alderson and general manager Zack Scott had decided to make a change even before Alonso transformed himself into “Donnie.” Alonso, in fact, was among the Mets most upset by the firings, and admitted to crying at his locker after hearing the news. He also was emotional in two subsequent conversations with Scott, sources said. https://theathletic.com/2577809/2021/05/10/rosenthal-pete-alonso-behind-a-mets-mystery-the-red-soxs-unsung-hero-nick-madrigal-the-anti-2021-hitter/https://theathletic.com/2577809/2021/05/10/rosenthal-pete-alonso-behind-a-mets-mystery-the-red-soxs-unsung-hero-nick-madrigal-the-anti-2021-hitter/
