It’s Thursday and you know what that means.
Every week during the fantasy baseball season, we do a stock report looking at players whose value is rising or declining. If there are specific players you want me to dive into, feel free to tag me on Twitter.
Without any further ado, let’s get to it. Here are a few fantasy baseball players trending up and others on the way down.

Fantasy Baseball Stock Report (Week 13)
Stock Up
When Lewis is on the field good things happen. Unfortunately, we haven’t been able to see him play all too often. The 25-year-old has only played in 83 games over his three seasons in the majors.
He missed the entire 2021 season with an ACL tear he suffered in spring training, then suffered the same injury just 12 games into the 2022 season. He suffered a right quad strain on Opening Day of this season but has finally returned to the Twins’ lineup.
Since the beginning of June, Lewis has been leading the league in ISO (.479). He is third in wOBA (.512) and wRC+ (241). He trails only Carlos Santana and Ryan Jeffers in homers on the Twins despite playing in just 14 games this season. The former first-overall pick in the 2017 draft can put up an MVP-caliber season if he can finally play a full season.
Tanner Bibee is coming off his best start of the season against Seattle. The 25-year-old struck out 12 Mariners over just six innings of work while allowing just three hits, one walk and zero runs. He was pulled after 93 pitches.
In June, Bibee has the highest K% (44.8%) and the lowest xFIP (1.16). His BB% also ranks 21st in the league (4.5%).
He has had some easy matchups over his last few starts, including the aforementioned Mariners, who collectively strike out at the highest rate in the majors. His start before that he struck out 11 Reds over just five innings. Cincinnati strikes out at the fifth-highest rate in MLB.
His next start should come against Baltimore, who strike out in the bottom half of the league as a team and have a plethora of talent on offense. Either way, Bibee has proven to be a high-upside strikeout pitcher when the opportunity presents itself.
Heliot Ramos has been one of the best hitters in June. He ranks sixth in wRC+ (210), sixth in wOBA (.466) and fifth in ISO (.343).
At 24 years old, Ramos played just nine games in 2022, followed by 25 games in 2023. This season has been his best by far, however, as he leads the Giants in just about every offensive metric. His nine homers are tied with Jorge Soler and Thairo Estrada for the team lead.
He was the 19th overall selection in the 2017 MLB Draft and he is finally able to show off his talent as an everyday center fielder in San Fransisco.
Stock Down
Adam Duvall has just five hits over his last 10 games and is batting just .173 with six homers on the year. In June, he is ranked seventh-worst in wRC+ (14), ninth-worst in wOBA (.186) and 14th-worst in ISO (.049). He is also striking out at 29.9%, the 22nd-highest rate in baseball.
For a guy who has historically been a lefty-mashing home run hitter, the power numbers are concerning. He’s been playing every day for a depleted Atlanta outfield as they deal with injuries to Ronald Acuna Jr. and Michael Harris Jr.
Perhaps a change of scenery would work better for the 35-year-old Duvall. For now, he’s been a big letdown for an already disappointing Braves lineup.
I thought Bryan Bello would be the ace of this Boston rotation coming into the season, but it turns out he’s been one of the least productive pitchers for the Sox this season.
In terms of xFIP, Bello is ranked behind Tanner Houck, Nick Pivetta and Cooper Criswell. His strikeout rate is just 20.4%, which ranks dead last among all Red Sox starters.
In June, his xFIP ranks 14th-worst amongst all qualified pitchers in baseball at 4.46. He is just 25, but the six-year, $55 million contract he signed in March is starting to look regretful.
Leody Taveras is one of two hitters with a negative wRC+ in June. His mark of -19 puts him ahead of just Andres Gimenez who sports a -2.
Many of these Texas bats have been cold over the last few weeks, as both Adolis Garcia and Ezequiel Duran join Taveras in the bottom 23 in terms of wOBA in June. Taveras has also been striking out a concerning 30% in that time frame. Through 143 games last year, he had a K% of 21.2%.
The reigning World Series champions sit with an underwhelming 34-40 record on the year and will need more help from these offensive pieces if they want to make an October run again this year.
