Taj Bradley Underdog MLB Pick: Higher Than 6.5 Strikeouts
It’s very, very crazy how well he’s pitching. Since June 8th, a nine-game span, Bradley’s pitched to a 0.82 ERA while allowing a .182 AVG and a 30.8% K-rate. The strikeouts are what we’re looking at here as he faces a Marlins team that just traded EVERYONE.
In July, the Marlins had the sixth-highest K-rate at 24.9% against right-handed pitching. Bradley’s gone over this mark in three of five games.
Nick Castellanos Underdog MLB Pick: Higher Than 1.5 Total Bases
Let’s start with this. Has there been anything noteworthy happening in the world? If so, bet on a Castellanos home run. If not, we can simply take the total bases and run. Nestor Cortes has NOT pitched well at all on the road. He has a 6.18 ERA on the road compared to 2.48 ERA at home.
He’s also allowed a .313 AVG, .388 wOBA and 1.63 HR/9 which are all significantly higher than his home numbers. Righties have also given him fits on the road allowing a .321 AVG, .603 SLG% and .411 wOBA. Castellanos, over the last two months, has hit .293 with a .933 OPS, .293 ISO and .384 wOBA against southpaws.

Player News
Daulton Varsho picked up three hits, three RBI and a homer in a win over the Angels on Thursday.
Varsho has only played in seven games this year, but they’ve been seven good ones. He’s homered three times already, and his slugging percentage is a remarkable — and entirely unsustainable — .727 over 22 at-bats. Varsho has been a mediocre offensive player in his two seasons with the Blue Jays, but it’s possible at the age of 28 he’s having a breakout campaign. Far from a guarantee, but possible.
Taylor Ward hit a two-run homer in a loss to the Blue Jays on Thursday.
Ward, 31, gave the Angels a 2-0 lead with a two-run homer off Chris Bassitt in the first inning. He’s now gone deep in two of his last three games, and it ‘improves’ his slash to .181/.224/.391. Ward has been one of the most hot/cold players players in the sport over the last few years, so fantasy managers who can afford to make some roster moves may want to look at Ward while the going is good.
Vladimir Guerrero Jr. picked up three hits and scored twice in an 8-5 win over the Angels on Thursday.
Guerrero also drew a walk. It gives the first baseman multiple hits in back-to-back games, and it’s the third time in May that he’s reached that mark. That’s helped raise his average from .268 to .295, and the only thing fantasy managers can be disappointed with is his .432 slugging percentage. That number should continue to climb as the season unfolds, but Vladdy Jr. has had some inconsistent seasons when it comes to power production.
Chad Green picked up his first save of 2025 with a scoreless ninth against the Angels on Thursday.
Green got the save after Jeff Hoffman worked in back-to-back games — and struggled — in the first two contests against the Angels. He struck out two and looked the part while needing just nine pitches to get through the inning. Hoffman should remain the closer, but Green is on his tail if the struggles were to continue.
Chris Bassitt allowed five runs — four earned — while working six-plus innings against the Angels on Thursday while picking up a win.
Bassitt allowed three runs over the first two innings on a pair of homers, but settled down over his next four frames. He came out to work the seventh, but ended up being charged for two more runs after leaving the contest. The 36-year-old veteran has forged a 3.35 ERA and outstanding 49/8 K/BB ratio over the first quarter of the season, but this wasn’t him at his best. He’ll get the Rays next week if the rotation order stays the same for Toronto.
José Soriano allowed three runs over five innings while not factoring in the decision Thursday against the Blue Jays.
Soriano left with a 4-3 lead, but it was erased quickly after his departure. The 26-year-old was not exactly dominant in his outing with eight hits allowed and four free passes, but he did strike out six to help balance things out a smidgen. Soriano takes an even ERA of 4.00 into a scheduled start against the Padres in San Diego on Tuesday. There should be better options for that one.
