We haven't lost any of those trades yet.
Brown for Robertson - 0.7 WAR for Robertson, Brown still negative WAR so far.
Tait and Abel for Duran - 1.7 WAR so far for Duran (in 30 games), Abel 0.1 WAR since the trade. Tait is 19; so way too early to know what he will be.
Lee for Lorenzen - -0.1 WAR for Lorenzen, -0.1 WAR so far for Lee
Klassen (and Aldegheri) for Estevez - 0.6 WAR for Estevez, -0.3 WAR so far for Klassen
Mendez (and Villoria) for Bader - 1.3 WAR for Bader, Mendez is in AA
Bergolla for Banks - 1.9 WAR so far for Banks, Bergolla is only 21 (his 1.096 OPS is in 10 games; he was .675 in AA)
Caba (and Boyd) for Luzardo (and McIntosh) - Luzardo 3.6 WAR so far, Caba is 20 at A+
O'Hoppe for Marsh - Marsh 9.2 WAR since the trade, O'Hoppe 3.0
Moniak (and Jadiel Sanchez) for Thor - 0.6 WAR for Thor, 1.6 so far for Moniak
OK, maybe we lost the Moniak trade, but so far he's a half WAR per year guy, and he'll be 28 next month; so I'm not upset.
The players we got are some 15 WAR ahead of the guys we gave up so far. Of course, some of the young players who haven't made the majors or have just started playing in the show will undoubtedly have some positive value. But Duran, Marsh, Luzardo, and Banks are also still producing.
Overall, so far that's a good set of trades for the Phillies.
