Includes Detailed Projections

Outlook Riley O'Brien

O'Brien remains a solid saves source despite recent traffic on the bases.

The second-place Cardinals (40-32) continue to lean heavily on O'Brien as their primary closer, especially with Ryan Fernandez currently sidelined on the injured list. While he has managed a tidy 2.25 ERA over his last 14 days, an elevated walk rate has bloated his WHIP to 2.00 during that span. Despite the constant traffic on the bases, his job security in the ninth inning remains completely secure.

Although O'Brien's 1.98 WHIP over the past 30 days suggests regression, our projections expect him to settle down. Our models forecast a 3.71 ERA and a 1.32 WHIP over the rest of the season, which is right in line with his current 3.94 ERA and 1.28 WHIP. His high-octane strikeout capabilities will continue to help him escape jams.

With three remaining road games in Kansas City this week, O'Brien is projected for 2.4 saves according to our data. Facing a competitive Royals squad sets up several tight, high-leverage late-inning opportunities where he can shine. Lock him in as a priority option in all active formats. Verdict: Start.

Outlook Robert Suarez

Suarez Anchors Braves Bullpen with Dominant Late-Inning Work

Robert Suarez continues to shut the door in the late innings, delivering pristine ratios and locking down close games for a highly competitive Atlanta Braves club. Operating as the primary high-leverage weapon at the back of the bullpen, his high-90s fastball and devastating changeup have kept opposing hitters completely off balance. With the Braves firmly in the postseason hunt, his high-leverage opportunities remain incredibly frequent and highly valuable.

The underlying metrics fully support Suarez's success, as his excellent strikeout-to-walk ratio and ability to limit hard contact align perfectly with his strong career baselines. While any reliever is prone to brief stretches of ratio inflation, his steady underlying performance suggests his current run is entirely sustainable. Expect him to continue providing elite WHIP and ERA stabilization alongside a steady stream of saves and holds.

Looking at the upcoming schedule, Atlanta faces a slate of competitive matchups that should yield plenty of close-game, high-leverage situations for the bullpen. Fantasy managers can comfortably lock him into weekly lineups expecting multiple save opportunities and clean innings of relief with strong strikeout upside. He remains a premium, must-start option in all standard and deep fantasy formats. Weekly Verdict: Start.
