Top Waiver Wire Adds: July 30, 2026

Heliot Ramos, OF, San Francisco Giants

Four hits, three RBI, a run, a walk, and a stolen base in Wednesday's blowout win over Milwaukee. Yes, it was against the Brewers and yes, box scores in 16-3 games are always a little inflated — but Ramos has been one of the more quietly productive outfielders in the NL over the last few weeks.

He's still not getting enough respect in fantasy circles. The Giants have been scoring runs, he's hitting in a good spot in the order, and the speed-power combination makes him a genuine two-category contributor. If he's sitting at under 50% ownership in your format, that's a mistake you should correct before the weekend.

Quinn Mathews, SP, St. Louis Cardinals

This one's forward-looking, but act now. Mathews has reportedly been removed from the Triple-A Memphis rotation schedule, which is usually the clearest sign that a call-up is coming. The Cardinals have rotation questions and Mathews has been one of the more intriguing pitching prospects in the upper minors.

He's going to be owned quickly once the news drops. Stash him now in any league with bench spots, especially deeper leagues and dynasty formats. The window to grab him cheap is closing fast.

Max Clark, OF, Detroit Tigers

The Tigers are calling up their number two prospect — No. 32 overall — for Friday. Clark had a dominant July at Triple-A Toledo and the Tigers are clearly signaling it's time. Detroit's outfield situation has been a revolving door all year and Clark is about to walk through it.

He's one of the more electric young talents in the minors with a profile that translates — good contact skills, speed, developing power. There will be an adjustment period, but in dynasty leagues he's an absolute priority add. In redraft, take a shot if you have the roster flexibility. Getting in early on a top prospect's debut is how you win waiver wire wars.

Matt McLain, 2B, Cincinnati Reds

McLain is back off the IL after a calf injury. He didn't miss a massive chunk of time, but he was sidelined long enough to lose some ownership in shallower leagues. That's your opening.

When healthy, McLain is a legitimate fantasy contributor at second base — a position that's always thin. He's got speed and he hits at the top of the Reds' lineup when he's right. Get him back on your roster before he reminds everyone why he was worth owning in the first place.
