Money wasn't spent as freely this week relative to earlier periods, but the number of bids this week made for quite an active waiver wire.

Here's a summary of this week's FAAB action:

Joe Bartel paid up to get a boost in the saves category, landing newly anointed closer Brad Ziegler for $15. The sidewinder's first game back from the disabled list certainly wasn't great, as he gave up two hits without striking out a single batter, but a save is a save, and as long as Kyle Barraclough (shoulder) remains on the shelf, Ziegler's ninth-inning experience should help him maintain the closer's role and help Bartel make up some ground in the saves category.

Outside of Ziegler, Marco Estrada wound up being the most sought-after player with a whole two bids totalling $5. Although Josh Rudd managed to nab him for a mere $3, the 34-year-old starter is a nice grab likely worth more than that given the dearth of quality options in the free agent pool at this point of the season. Estrada allowed just three runs over his past two starts, and despite the fact that he doesn't have any wins to show for it in that span, there's a decent chance that he could be traded to a contender who could give him better run support. He also has a two-start week on tap in leagues with a Thursday/Friday lineup period like ours, which could help swing Rudd's squad up in several pitching categories.

The top hitter grabbed this week is a very interesting find. Tim Heaney picked up outfielder Leonys Martin, whom you might remember as the scuffling veteran who was cast off the 40-man roster earlier in the season. The 29-year-old is back with a vengeance, as he collected five hits in his first 13 at-bats after his stretch in the Pacific Coast League. He also possesses plenty of speed (20+ steals in three of the past four seasons), so if he can maintain his regular role in the Mariners' lineup while Mitch Haniger (face) is sidelined, Martin could be a savvy move that helps keep Heaney afloat at the top of the league standings.

There was no question who the busiest owner was this week, as D.J. Trainor scooped up a whopping six players as he retools his roster for the future. As the Rockies beat writer for RotoWire, I naturally have a soft spot for Pat Valaika (or "Patty Barrels" as he is better known by the LoDo faithful), but the free agent pickup I like the most in this instance is reliever Taylor Rogers. He's just 26 years old, and with Brandon Kintzler out of Minneapolis, Rogers is in line to act as the Twins' closer for the time being. Just like many of the Twins' relievers, he's had his fair share of struggles, but his value is certainly boosted by the fact that he's getting the first crack at ninth-inning duties.

This week, we'll finish things out by flipping the script and focusing on a rebuilding squad. Likely more known for his fantasy football advice, Mario Puig has done a great job acquiring young talent to create a formidable 2018/2019 roster. His team boasts top prospects such as Yoan Moncada, Gleyber Torres and Eloy Jimenez as he quietly stocks up for future dominance.
