Michael Lorenzen made quite the first impression to the Philadelphia Phillies fans.

Lorenzen threw the 14th no-hitter in Phillies' franchise history on Wednesday in Philadelphia's 7-0 win over the Washington Nationals in his first start at Citizens Bank Park in a Phillies' uniform.

Acquired by Philadelphia from the Detroit Tigers at the trade deadline, Lorenzen struck out five and walked four while throwing a career-high 124 pitches in just his second start for the Phillies (63-52).

He got Dominic Smith to fly out to shallow centre field to record the fourth no-hitter in MLB this season and the first by a Philadelphia pitcher since Cole Hamels in 2015.

Selected to his first All-Star Game this year, the 31-year-old Lorenzen improved to 5-1 with a 1.11 ERA and 0.76 WHIP in six outings since the start of July, which includes his final four appearances for the Tigers.

While Lorenzen shut down Washington (50-65), a couple of Philadelphia batters hit milestone home runs.

Nick Castellanos hit a pair of homers to give him 200 in his career, while Weston Wilson homered in his long-awaited first major league plate appearance.

The 28-year-old rookie had 2,836 plate appearances in the minor leagues before being called up Sunday.

The Phillies have won four of five, scoring seven, eight, eight and nine runs in those victories.

Raleigh's eighth-inning homer powers Mariners to seventh straight win

The Seattle Mariners continued their August surge, extending their season-high winning streak to seven games with a 6-1 win over the visiting San Diego Padres.

The score was tied 1-1 heading into the bottom of the eighth inning before the Mariners (62-52) erupted for five runs, taking the lead on Cal Raleigh's tiebreaking two-run homer with one out.

Mariners top pitching prospect, Emerson Hancock had an impressive major league debut, allowing a run and two hits over five innings.

The 24-year-old right-hander struck out three and walked three, and combined with five Seattle relievers to four-hit the Padres (55-60), who have lost four in a row.

Seattle, meanwhile, has lost just four games since July 20, going a major league-best 15-4 in that span to move a season-high 10 games over .500.

Ohtani earns 10th win as Angels top Giants

Shohei Ohtani picked up his 10th win of the season, yielding one unearned run over six innings of three-hit ball in the Los Angeles Angels' 4-1 victory over the visiting San Francisco Giants.

The major league leader in home runs, Ohtani struck out five and walked three, becoming the first player in MLB history to have multiple seasons with 10 or more homers and 10 or more wins.

The two-way sensation, who won 15 games in 2022, has not allowed a run in 19 innings over his last three starts, lowering his season ERA to 3.17.

Ohtani has been stuck on 40 homers since August 3, and went 0 for 2 with two strikeouts at the plate against the Giants (62-53), though he did walk twice and scored on Mike Moustakas' tiebreaking three-run homer in the sixth inning.

Moustakas had two hits, and has driven in 10 runs in his last seven games for the Angels (58-58), who have won two in a row following a season-high seven-game losing streak.
