Rookie Sensation is a son of the late Unbridled’s Song out of a mare from the sire-producing female line of A. P. Indy and Summer Squall, etc. Unbridled’s Song is emerging as a sire-of-sires with six of his sons having sired Grade 1 winners so far.
In Reality-influenced mares went extremely well with Unbridled’s Song to the tune of at least 14 stakes winners, seven of them Grade 1 winners, including his most recent two - Breeders’ Cup Mile champ Liam's Map and Arrogate. In addition, eleven sons of Unbridled’s Song have now sired stakes winners out of mares showing In Reality.
Unbridled’s Song over Deputy Minister has produced a high degree of quality, with 2016 Travers S. (G1) dominator Arrogate the latest example. His second dam is by Deputy Minister while Eclipse Award champion Will Take Charge is among the pair of Grade 1 winners Unbridled’s Song sired with daughters of the Deputy Minister son Dehere. G1W Majestic Harbor is by an Unbridled’s Song son out of a mare by French Deputy. That Deputy Minister stallion is also damsire of a Grade 2 winner by Unbridled’s Song’s Songandaprayer. Daughters of the Adena Springs-affiliated Deputy Minister sons Awesome Again and Touch Gold have contributed to the success of this cross as well.
Unbridled’s Song and his sons have sired at least 26 stakes winners (three G1 winners) out of mares showing Nijinsky II. The Unbridled's Song line has produced a similar number of stakes winners with mares carrying Danzig. There are a trio of G1 winners in that group, including Breeders' Cup winner Ria Antonia and Arrogate.
Storm Bird/Storm Cat
are other Northern Dancer
-line influences that should go well with Rookie Sensation. Unbridled’s Song and 10 of his sons have sired over 36 stakes winners out of Storm Bird-line mares. This sample includes four Grade 1 winners by Unbridled’s Song and MG1W Close Hatches by an Unbridled’s Song son.
Daughters and granddaughters of Giant’s Causeway
have yet to participate on the success of the cross but are certainly interesting (including mares by the Adena Springs North stallion Giant Gizmo
). The reverse of the Unbridled’s Song/Giant’s Causeway cross has yielded four group/graded winners including MG1W Carpe Diem. In addition, we find Nureyev (Rookie Sensation’s maternal grandsire) and Giant’s Causeway together in the pedigrees of nearly 50 stakes winners and seven Group/Grade 1 winners around the globe.
Unbridled’s Song and his sons are clicking with a select strains of the Mr. Prospector
line, namely Forty Niner and Gone West. Arrogate is out of a daughter of the Forty Niner
son Distorted Humor
, also the damsire of a stakes winner by Unbridled’s Song’s Even the Score. Liam’s Map is out of a mare by the Forty Niner grandson Trippi
Ria Antonia is out of a daughter of the Gone West
stallion Mr. Greeley
, as are the 2016 Unbridled's Song GSW Market Rally and GSW Irish Jasper (by an Unbridled’s Song son)
is an example of the success of the Unbridled’s Song/Gone West cross. Overall there are at least 12 stakes winners and seven graded winners bred Unbridled’s Song over Gone West.
Unbridled’s Song has produced exceptional quality out of mares showing Hold Your Peace
. Arrogate and 2016 G1W Tara’s Tango give him five graded winners now with Hold Your Peace-influenced dams (the other three are Grade 2 winners). G1W Majestic Harbor, by an Unbridled’s Song son, is another headliner.
